Needing Advice

I had a missed miscarriage at 12 weeks & baby’s heart stopped at 9 weeks. I had a D & C in November. I extremely messed over it. I have never had to experience this & yes I know I am lucky as I already have 3 children. It’s been 3 months since and My depression is 10x worse than when it happened. My husband is currently deployed, he left at the beginning of January. I have been so short tempered with all my kids and feel horrible. I feel like I have certifiably gone crazy. I have bipolar disorder and anxiety, but it has been managed at stable for the last 3 years. I don’t know what to do. I have already talked to my psychiatrist and all she suggested was therapy. I have a therapy appointment next Monday, but I feel there’s no way there’s anywhere up from this. I feel like I can’t get a chance to catch a break and actually deal with it. Especially being military, there’s a lot on me as I am holding down an entire household while he is gone. Does anyone have any other advice ?
